Answer 1

Answer:

k = 30; y = 30/xy = 9; y = 36/xx = 5/2; k = 50y = 2; k = 24

Step-by-step explanation:

When we say "y varies inversely as x", we mean that y is proportional to the inverse of x: y = k·(1/x). This relation is usually written ...

  y = k/x

It can be solved for the other values:

  xy = k . . . . multiply by x

  x = k/y . . . divide by y

If you are given the equation, the value of k can be read directly from it: it is the constant in the numerator.

__

a)

  k = xy = 5·6 = 30; the equation is y = 30/x

b)

  y = k/x = 36/4 = 9; the equation is y = 36/x

c)

 k = 50 (read from the equation); x = k/y = 50/20 = 5/2

d)

  k = 24 (read from the equation); y = k/x = 24/12 = 2

Answer:

y = -5/9x + 4.1

(try doing this yourself first with different points to make sure this is the right answer, because im to lazy to check myself but ill try checking D:)

Step-by-step explanation:

first you have to find the slope . to do this use the equation y2 - y1/ x2 - x1

so write as -2 - 3/  -7 - 2 is equal to -5/-9

so now write y = -5/9x + b

we must now find the y-intercept so substitute one of the points given. lets substitute 2,3 it looks easier. So it will look like 3 = -5/9(2) + b

3 = -5/9(2) + b

3 = -10/9 + b

b = 3 + 10/9

b = 4.111111

um just round to the tenth place

Answer:

1/6

Step-by-step explanation:

This is conditional probability.

If heads is tossed, then and only then does he have the option to draw either green or red and have the full 'Head, Green/Red' combination.

So, the probability of the first event - getting heads, is 1/2, since either heads or tails can be flipped with 50/50 chance.

The probability of the second event - picking either green or red, is 1/3, since there are 6 colour options - blue, red, yellow, green, orange and purple - of which 2 can be chosen. Thus, 2/6, which simplifies to 1/3

Now since these are both independent events, we must multiply their probabilities.

1/3 * 1/2 = 1/6

The box plots show the average wind speeds, in miles per hour, for various cities in two different countries.

Find the product of (x + 5)(x - 5).
x2 - 10x + 25
x2 + 10x + 25
x2 - 25
x2 + 25

Answers

Answer:

x²-25

Step-by-step explanation:

Hi there!

We are given (x+5)(x-5) and we want to find their product.

As these are binomials, we can multiply them using FOIL, which is First, Outer, Inner, Last

So let's start with the firsts, which would be (x+5)(x-5), or the 2 x's; x*x=x²

Next, let's do the outers, which would be (x+5)(x-5); x * -5 = -5x

Now the inners; (x+5)(x-5); 5 * x = 5x
Finally, the lasts; (x+5)(x-5); 5 * -5 = -25

Now add all of these terms together:

x²-5x+5x-25

We can combine the 5x and -5x together to become x²-25

So the answer is x²-25, which is a difference of squares expression (if we have (a-b)(a+b), then the result is a²-b²).

Hope this helps! :)

Answer:

5/5

Step-by-step explanation:

if you want to divide 1 whole into a fraction then the top number would have to be the same as the bottom number, for example 5/5. The top number is 5 which is the same as the numerator which will equal to 1 whole.

While 1/5 and 3/5 is less than 1 whole

Step 2 = 10 dots

Step 3 = 13 dots

Using it's concept, it is found that there is a 0.04 = 4% experimental probability of rolling a 5 on the red number cube, NCI, and a 2 on the blue number cube, NC2.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In an experimental probability, these number of outcomes is taken from previous trials.

Researching this problem on the internet, it is found that out of the 250 rolls, 10 resulted in a 5 on NC1 and 2 on NC2, hence:

p = 10/250 = 1/25 = 0.04.

0.04 = 4% experimental probability of rolling a 5 on the red number cube, NCI, and a 2 on the blue number cube, NC2.
